Abstract
The primary objective of urban planning is to enhance the quality of life for residents. However, inadequate implementation can increase communities' vulnerability to natural hazards, such as floods. This study examines land use along the rivers flowing through Tabriz, particularly in deteriorated areas within these river boundaries. Given the influence of vegetation on urban flood management, changes in vegetation cover in these regions were evaluated. The river boundaries were categorized into three zones: 15 meters, 30 meters, and 500 meters, and changes in vegetation cover were analyzed using satellite imagery from 1980 to 2023, along with the calculation of the NDVI index. The findings indicated a significant presence of residential, commercial, and industrial land uses within the river boundaries. Furthermore, vegetation cover has been notably affected during the study period, particularly in the city center and at river confluences. Contributing factors to this degradation include negligence by urban planners and implementers, an increase in land use value, and the prioritization of certain societal segments in these areas. Approximately 70 percent of the buildings are deemed acceptable in terms of construction materials; however, Tabriz faces substantial flood risks due to inadequate management of river boundaries. Therefore, it is imperative to reinforce structures, particularly in degraded areas, and to revise land use policies. This research underscores the necessity for integrated urban planning that adheres to conservation principles to mitigate the risks associated with natural hazards.
